PAPER-BOX MACHINE.

SPECIFICATION forming; part of Letters Patent No. 546,318, dated September 17, 1895.

Application filed August 2, 1894:.

To all whom it may concern.-

Be it known that I, CHAUNCEY W. GAY, a citizen of the United States, residing at West Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Paper-Box Mashmes, of which the-following is a specifica- This invention relates to improvements in machines for making paper boxes, patented to me May 8, 1894, No.519,53l, the object being to render such machine more durable, effimeet, and certain in its operation.

The features of improvement relate to the [5 peculiar blank-conveyer in its combination with a part in connection with which it has a sliding support, and to devices which, in combination with the conveyor, serve to cause the blanks to be squared and guided strictly 2 to their required positions over the throat of the folding devices.

The invention consists in the constructions and arrangements of parts, all substantially as W11]. hereinafter fully appear, and be set forth in the claims.

In the drawings, Figure 1 is a perspective view of the upper part of the paper-box machine which forms substantially the subjectmatter of the aforesaid patent with the prescut improvements applied thereupon. Fig. 2 1s a plan View of sufficient of the parts of the machine to show the present improvements in the conveyor and the support and bufier devices therefor. In this view a box-blank is shown as conveyed to its position over the folding-throat. Fig. 3 is an inverted plan view of one of the members, which is adjustably affixed to each of the conveyor-bars and with which a transversely-applied rod has a 0 free sliding engagement.

In the drawings it will be perceived that the throat to under the folding-plunger F, at which the folding is to be performed, is constituted by the vertical plates D D, mounted on slides to approach and recede from each other, and the reciprocatory followers B B, which are operated by toggles 28.

The conveyor comprises the horizontal bars h h. These, as fully set forth in said patent,

Serial No. 519,239. (lilo model.)

for in the tops of the end followers 13 B, and in addition to their longitudinal movements the conveyor-bars 72 h have, necessarily, movements transversely of their lengths by reason of the reciprocatory movements of the follow- 5 5 ers B B, and to permit this action the driving connection for the conveyer-bars is had by afiixing at or near the rear end of each bar it the collar 75 7 5 with the right-angularly-perforated member '76, through which the crossrod 78 has the sliding connect-ion. Said crossrod receives its movement bodily and transversely of its length by the driving connections, substantially such as heretofore employed and set forth or as usual in conveyors 6 for envelope and analogous machines, although in this machine the driving connections are duplicated, so that both ends of the rod will be compelled to move in unison and always in a line at right angles to its length.

Upon the rear central portion of the table of the vmachine is mounted an L-shaped bracket M, its horizontal member 'm rearwardly extending and serving as a support for the cross-bar 7 S, on which the same may rest and slide. The said horizontal member m has at its rear extremity the buffer, preferably consisting of a block of rubber m against which the bar in reaching the limit of its rearward movement may abut for a yielding resistance and a definite limitation of the rearward movement of the said bar and the conveyor as a whole.

The buffer is a fixed point. The conveyor always has the same throw, and for the ad- 8 5 justment of the conveyor to meet the require ments arising by running the machine for various sizes of boxes the bars h h are adjusted with relation to said rod 78v to accord with such different sizes. Thus for a wide box the go conveyors h project farther forward than for a narrower box. This adjustment when made is maintained by the set-screws 80.

There are ranging longitudinally above and parallel with the followers B B two guide- 9 5 plates, (seen aim 1%,) the forward extremities of which are deflected outwardly from the path of the blank in moving from the pile at q to its position to be upbent under the plunger.

50 move longitudinally through slideways therel Each of these guide-plates his carried at the too displacement which the blank may acquire as it is moved to its place under the plunger. They also serve to prevent any shifting of the blank when the same rests on the top of the movable throat members and when such members have their movements of separation or approach.

The blanks, which are shown in the pile at 1 have their corner portions cut out, as seen at The position of the gum-box (not shown) is over the front of the pile in this machine, as customary for locating such gumbox in envelope-machines, and the bottom of this gum-box forms the support for the bars 16 it, which are secured by the screws a n These are longitudinally slotted, as seen at U3, and serve as the supports on which are the transverse strips '0 e, which have the depending extremities 12 c These strips 1; o are, longitudinally of their length, slotted, and by the screws or clamps at 12 they are suitably adjustably confined on the slotted support-bars it to, while their overlapping terminal portions are confined by the clampscrew i).

The depending members "0 e have their positions in line with the cutouts or recesses at the corners of the blanks, so that as the blanks are raised by the gummers and detached to fall upon the conveyor, then thereunder, the so-detached blank will be restrained from any shifting either laterally or toward the front of the machine by said parts 71 12 By moving the transverse strips t; v longitudinally of the bars a tt and by telescoping the transverse strips one relative to the other the depending members 41 12 may have their positions to accord with the blanks of any given dimension.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is

1. In the paper-box machine of the character specified, the combination with the reciprocatory followers, 13,13, and the conveyorrods, h, h, mounted in ways of the followers, movable in unison with them, and also movable endwise through them,of members adapted to be confined along the lengths of said rods, the cross-rod, 78, having a free sliding engagement through said adjustably confined members, the stationary horizontal bar on which said rod, 78, is supported as it moves, and which has the buffer, m fixed thereon, all substantially as and for the purpose set forth.

2. In a paper box machine, the combination with the movable members constituting the contractible throat under the plunger, and the blank conveyer of the strips, n, n, arranged in parallelism at opposite sides of, and above, the said coutractible throat and having the outwardly deflected forward ends, substantially as and for the purpose set forth.

3. In a paper box machine, the combination with the movable members constituting the contractible throat under the plunger, the blank conveyor, and the supports, as the uprights of the arch, Q, having the transverse socket holes, n if, of the rods passed through and adjustably confined in said socket holes, which are provided at their inner ends with right angular strips, or plates, at, n, the forward end portions of which are outwardly deflected, substantially as and for the purposes set forth.

p at. In a paper box machine of the character described, the combination with the conveyers, h, 71, of the horizontal, longitudinally ranging bars, u, 16, with the slots, u and the transverse slotted strips, '0, o, having the depending members, 172, and the clamp-screws, v2 '0 adjustably confining the slotted strips, '1], in different endwise positions along the length of the bars, 16, substantially as described.
